Abstract
The invention is related to a method of manufacturing a platinium electrode that has high porosity and current density of above 10 mA/cm2. The method comprises adding particles of a high temperature fugitive material such as carbon to the platinum ink, and subjecting the mixture to high temperature sintering to remove carbon powder thereby leaving small voids in the platinum.
